Comment: This certified cobalt spinel comes with sharp edges and a reclusive color character. Like some humans it needs light and time to be comprehended. Once you have seen the fantastic blue (which the images capture in a spotlight) you will not want to miss it. Thus be aware before you look closer: this is not a stone for love on first sight but something you will learn to cherish over time. Free of inclusions, 9x9mm, no window, cold metallic blue. See big images for different tones and light settings.
